bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.It only compresses single files and is not a file archiver.It relies on separate external utilities for tasks such as handling multiple files, encryption, and archive-splitting.
The most widely used lossy compression algorithm is the discrete cosine transform (DCT), first published by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974. Lossy compression is most commonly used to compress multimedia data (audio, video, and images), especially in applications such as streaming media and internet telephony. By contrast ...
Most raw formats implement lossless data compression to reduce the size of the files without affecting image quality. But some others use lossy data compression where quantization and filtering is performed on the image data.

Biden has already wiped away more than $175 billion in loans for millions of student borrowers, as part of a 2020 campaign promise to eliminate their debt.
Johnson has shown urgency to get legislation passed despite Trump's shifting position as the speaker and president-elect continue to work together to deliver on Trump’s ambitious promises during ...
Quantization, involved in image processing, is a lossy compression technique achieved by compressing a range of values to a single quantum (discrete) value. When the number of discrete symbols in a given stream is reduced, the stream becomes more compressible.
A Philadelphia man who was given a $4.1 million settlement after serving 24 years in prison for a murder conviction that was scrapped confessed to a separate killing -- over a paltry $1,200 drug debt.
